Specincation of Lettera Patent.

Application led March 16, 1917. Serial No. 195,104.

l To all 'whom t may concern Be it known that I, MAXIMILIAN .l FUCHS, citizen of the United States, residing at Stamford,v in the county of Fairfield -and State of Connecticut, have invented certain new and useful Improvements in Machines for Making Bronze-Powder; and I do hereby declare the following tobe a f ull, clear, and exact descri tion of the invention, such as will enable ot ers skilled 1n the art to which it appertains to make and use the same.

M invention relates to machines for making ronze powder, and is an improvement on my former Patents 647,081 and 681,447, wherein onlyr a limited number of grades of powder could be discharged from the mor- In my present improvement I have provided means whereby an indefinite number of grades of the powder can be selected at will. It is often necessary to temporarily arrest the operation of the beaters to fill a hurried order for powder of a certain quality which 'could only be done formerly by first manually removing the material already in the mortar-s, which process was not only slow but 'it also entailed quite a, loss of the finer product when exposed to the outer air currents.

Referring to the drawings:

Figure 1 represents albrokenside elevation oartly in section of a bronze powder bea! g machine;

File' 2 is an enlarged broken elevation of Fig.- f1 is an enlarged sectional view of the mortarson line3'-3 ofFig.2;`

4 is en enlarged detail view of one of the graduating slides; and 4 l Figl 5 is an enlarged- .mpper detail plan vlew of hopper for receiving the powder to be rebeaten and means for conveying 1t to the mortars and means for intercepting the flow of unfinished material to the morters.

A brief description of the general construction and operation of the machine for makingbroncepowder-willbev order to show the aforesaid im rovemen and the advantages derived the y..

1isthednv1ngdhafu2thednvmgpulle; 8 beaters operating in the mortals 4, m beaters are'eleva-tedpby the rotatable l -shafts and'anddropby gravlty on the anvils 48.

9 is thehopper inh which the metal to be treated is first plared and is conveyed therefrom tothe mor-ters by worms located in the extension 10, one of said worms, 11, beingshown in Fi 3. 12 is one of the worm shafts and the ot er worm Y shaft-not shown-is driven from the sprocket wheel 13 and chain 14. The rotation of these shafts is effected by means of the s rocket wheel 15, chain 16 and sprocket whee 17 on the worm shaft 18 mounted in the removable plate 19. 20 is a shaft rotatabl connected to the worm shaft 18, in an or nary mannernot shown-and 21 is a sprocket chain transmitting power to the worm shaft 12.

22 is a sprocket wheel mounted on the shaft 23, and said wheel is mtated through the medium 'of the sprocket wheel 2li-on the worm shaft IB-Yand the chain 25, Sprocket wheels 26-27 and chain 28 transmit motion to the shaft 29 carrying the gear 30 meshing with the pin-ion 31 on the worm shaft 32.v The beaten material out of the mortals into the recessed ront plate 19 and is carried by the worm 32 into the spout33 and isA delivered into the casing 34 from whence it is carried by thil endless bucket chain 35 into the hopper 36, and

from thenpe it is delivered through the spout 37 into the inclined rotatable sieve 38 located in the cabinet 39. The-finer particles are received by the hop r 40 and discharged into thedrawer 41, t e eoarser particles being returned to the mortars to be rebeaten.

In my .former constructions, these coarser particles were carried by gravi-ty from the end of the sieve to the hopper 9, and no provision was made to intercept this continuous crculati flow of metal until all of the metal innm mortals was exhausted by this beating and mbeating process. Nor,"as before mentioned, was any temporarily and automatically removing the unfinished metal from the mortals to 4 give lace for metal of another uality except the aborous and wasteful m od of emptying the mortars by hand. 7

In my present oonstructiom the sieve 38 discharges the coarser articles into the ho per 42 at the bottom o which is located t worm 43, incased in the tube 44,- and .is returned thereby to the hopper 9. Thisl worm is from the worm shaft 12 b means of the sprocket wheels 415-46. and l in 47. At the bottom of the hopper 4 2, 1 and 5 is an opening 48 adapted to be `closed by the gate '49 whose han 1e 50 proyects outside of the cabinet 39. When necessary to remove a certain quantity of the metal and at any stage of the beating process, the gate 49 is tem orarily withdrawn, Fig. 5, and the extracto metal is deposited in the drawer 51, and the gate is then closed to permit the interrupted flow to be returned to the hopper 9. To automatically empt the mortars for the reception of metal o a diffe-rent uality, the gate is kept withdrawn until t e remaining contents 1n the mortars have been discharged into the drawer 51.

In my former constructions, as before mentioned, onl a very limited and a predetermined num er of grades of the eaten metal could be delivered from the mortars through separate outlets or ports, in the sides of the mortars. In m present construction, these separate out ets have been converted into the large outlet 52, Figs. 2 and 3, and the narrow outlet 53-see also Fig. 4-is provided in the vertically op erated slides 54, located between-the'outer face of the mortars and the inner face of the plate 19. v

Graduation marks 55 are provided on the face of the mortars, each mark representing a certain grade so that the slides can be readily adjusted with respect to their narrow outlets and the large outlets in the mortars and thus deliver a. grade of powder of any degree and color required. This feature, in connection with the before mentioned gate 49, will enablethe operator to readily extract, at any pe-rlod of the beatlng process` anv particular grade desired.

The slides 54, Figs. 2 and 3, are shown raised to the highest point to bring their outlets at the upper end of the large outlet 5240i the mortars. yThis position of the outlets 53 permits the finer particles of metal to escape when the fixed flan es 56 on the beater rods pass .down throu the floating particles of metal. The out ets in thefaoe of the mortars are deep enough to allow the escape of any commercial gradeof owder. In other words, the upper edge of t e outlets 52 represent the highest practical point at which the li hter and finer grades of commercial pow er can be delivered from the mortars, and the lower edge of said outlets represents the lowest practical point of delivery of the coarser grades.

H'avin thus described my invention what I claim 1s:-

In a bronze owder machine, a motor having a relative y large opening of an area to embrace the entire floating range of all metals in a side thereof, a slide covering said o ening so as to form a part of the mortar si e said slidehaving an opening of less width t 1an that of the mortar openlng but of substantially the same length as the length of the mortar opening, and meansto allow of vertical adjustments of the slide so as'to vary the relatlon of the slide opening with respect to the top and bottom of the mortar opening while maintaining a constant alined relation of the ends of the slide opening with respect to the ends of the mortar opening.

In testimony whereof I aiiix my signature.
